vTo all whom it may concern:

Be it known that I, LOUIS Vroron Rn- States, and a the county of haveroveollowresident of San Bernardino, in

ment's in Pipe-Wrenches, of which th f y inventlonis an lmprovement inpipewrenches; and it consists 1n certain novel con- I structionsandeombinations ofxparts hereinafter described and claimed. i.

. Referring 'to the drawings forming a part hereof, Figure 1 is aplanview of my improved means of a pin d thus formin .dles. throught e innerend ofthesame;,and Fig. 7

wrench. Fig. 2 is with the upper ring removed. Fig. 3 is a perspectiveview of one ,of the gripping-jaws. Fig. 4 is a section on theline 4 4.of Fig. 2. Fig. 5 is a detail perspective of one of the han- Fi .6 is avertical longitudinal section In the practical 'ap' lication of myrivet. \tion I provide a circ I ar frame, having cena circular openingand comowerring-shaped plates A A, spaced apart and divideddiametrically to form' symmetrical halves, a curved lug a/ bein securedbetween the plates of one half an between the plates of .the opposite ahinge-joint between the halves. A secon is secured between the plates atthe free end of the first half and rejects between the plates of thesecond ha f, 'alined perforations a being provided in the freeend of thelug and'in the ends of the plates for the "recepti on of a pin a forsecuring the free ends of the halves together. h Steel spacing-blocks B-are'provided between the .rin s, the inner edge of the blocks bein'incline the same direction, as at b, on a ine approximately tangent tothe inner e line of the incline being a chord of the ring, and containedentirely within the area thereof. A spring bf is secured to the end-of.the spacing-blocks, and bolts 1), extending through the rings and thespacing-blocks, secure the'gparts in their .p'reper position. i Y

cured thereto by means of an inclined slot 0' in the gripping-jaws,engaged by a screw 0 extending between the plates. The inclined slot 0is parallel with the inclined edge of the gripping-jaws, and the jaw isnormally retained in its inward position by the spring I)". I

By means of the inclined slot and the inclined edge of thespacing-blocks the grip pingejaws are constrained to'move upon a chordof the ring, the said chord being approximately tangent'to ence of thering.

Handles D, quadrantally arranged .upon the frame, are provided formanipulating the same, one of the handles D- being integralwith one ofthe spacing-blocks, the remaining handles being removable from the ring.The movable handles D'comprise a bar d, having integral therewith aplate d, projecting beyond the inner end of the bar and provided with anupwardly-projecting flange d on itsfree end, the opposite face of thebar be- (i having a downWardly-projectin flange (i secured to-the bar bymeans of the hioges d, the flanges of the plates being adapted to emgage the recesses 07 on the ring. A transverse recess (1 is providedinthe bar'for the reception of a transverse lug d on the lower "face ofthe bin ed plate. A latch (i is hinged ace of the hinged plate and.

to the lower traverses an opening 1 through the bane spring d beingprovided on the latch for actuating the same. Grooved wheel-sections Fare secured to the free ends of the arms, the said sections beingadapted to receive a belt from a source of power.

The wrenchis designed especially for use in oil-fields, as in the uttingdown of pipelines, and is arranged can, however, be changed for use onsmall pipe by removing the ripping-jaws and in-' serting larger jaws int re p ace thereof, thus decreasing the'circular o ening between thefaces of the jaws. In or er that this may be easily accomplished, thejaws are retained in traversing the rings and the I It will be evidentfrom the description that. my invention while simple in construction isyet eflicient in operation, and can be cheaply constructed, nocomplicated mechanism forming part of the wrench. The handles are easilydetached. I Hence the wrench may be used inn limitedspace, andwhen thepipe? the inner circuinfen ing recessed to receive a second flangedplate when' it is desired tofnanipulate the wrench or large-sized pipe.It

are pro erly seated and started power may be use to turn the wrench bymeans-017a belt engaging the wheel-sections.

The wheel-sections on the handleare made removableybeing used only whenpower is used to turn the wrench. In ordinary use but two of the armswould be used, although it is evident that all might be used. c

' Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

1. A pipe-wrench comprising upper and; lower ring-shaped lates, spacedapart and divided diametrically into symmetrical sec tions, curved lugssecured between the corresponding ends of the sections, and extendingbetween the plates of opposing sections, pins j traversing the platesand the lugs for -securends, means for connecting the freeends of thering-shaped frame, comprising two symmeting the sections together, aseries of spacing- 5 blocks secured between the plates of the seeitions, and provided with an inclined inner; edge, springs secured to theends of the: blocks, gripping-jaws provided with inclined edges restingon the inclined edges of the blocks, and provided with transverse slotsparallel to their inclined edges, screws traversin the plates of therings and the slots,

hand es quadrantally arranged on the ring and comprising each a barprovided with a flanged plate, an oppositely-disposed flanged latehinged to the bar and eoactingwith the st flanged plate to form a recessfor rcceiving the rings, a lug on the second date engag 1 ing the groovein the bar, a'latc hinged to; the second plate and traversing an openingin the bar, a spring on the latch, and grooved wheel-sections on thefree ends of the bars.

2. In a pipe-wrench, the combination of a ring-shaped frame divideddiametrically and the sections hinged together at one of their sections,a plurality of spring'actua'ted gripping-jaws, slidab'ly mounted in theframe, a plurality of handles radiating from the frame, an means wherebythe individual handles maybe detached from the frame.

3. In a pipe-wrench, the combinationof a rical sections hinged togetheratone of their ends, means for securing the free ends of the g sectionstogether, a plurality of spring-actuated gripping-'aws movably mountedin the frame, and a p urality of detachable handles engaging the frame.

a. In a pipe-wrench the combination of a ring-shaped frame comprisingtwo symmetrical sections hinged together at one of their ends, means forsecuring the free ends of the halves together, a pluralityof-spring-actw ated gripping-j aws movably mounted in the frame, andmeans for constraining the movement of the jaws to a chord of the ring.

5. In pipe-wrenches, the combination of a circular frame having acentral opening, a plurality of spring-actuated grip ing-jaws movablymounted on the frame an P1016013- ing into the central opening, andmeans for. restraining the movement of the jaws to a chord of thecircular frame. f

6. In a pipe-wrench, the combination of a circular frame having --acentral opening adapted toreceive a pipe, a plurality of spring-actuatedgripping-jaws movably mounted in the frame and projecting into thecentral opening, and means for restraining the movement of the operativeface of the -j awe to a tangent of the pipe.

7. ringshaped frame comprising two symmetrical sections hinged togetherat one of their ends, means for securing the free endsof the halvestogether, and a plurality of spring-actuated gripping-jaws movablymounted in thcrframe, and 1profiecting beyond the inner circumference othe ring. a

8. In a pipe-wrench, the combination of a circular 'frame having acentral 0 ening adapted to receive a pipe, and a plum ity of spring-actuated gripping-jaws movably mounted in the frame and projecting intothe central openingmx-n I 9. In a pipe-wrench, the combination of acircular frame having a central opening, a

plurality of gripping-jaws projecting into the' central openmg, andmeans on the periphery of the frame for receiving a belt whereby torotate the same.
